ACFT EQUIP PROB JAMMED SPOILER HANDLE.

Narrative

ACFT WAS GIVEN A DSCNT CLRNC AND A VECTOR TO INTERCEPT THE FLL 042 DEG RADIAL. THIS RADIAL WAS NOT PART OF THE HEATT ARR AND THE CTLR WAS QUESTIONED WHEN RADIO CONTACT PERMITTED. WE WERE CLRED DIRECT HEATT AND GIVEN A NEW ALT RESTR THAT REQUIRED USE OF DRAG DEVICES. THE FO ATTEMPTED TO DEPLOY SPOILERS AND THE HANDLE WAS JAMMED. WE ATTEMPTED TO INFORM THE CTLR WE WERE UNABLE TO MAKE THE RESTR. THE CTLR WENT FROM ACFT TO ACFT WITH CLRNCS AND THE CREW WAS UNABLE TO MAKE CONTACT UNTIL WE WERE PAST HEATT AND HAD MISSED THE ALT. WE TRIED TO SQUAWK 7600 TO GET THE CTLR'S ATTN AND DIALED IN 7500 IN ERROR. THE CTLR MADE NO REF UNTIL THE CREW LATER ASKED IF THE SQUAWK WAS OBSERVED. WE INFORMED MIA APCH OF WHAT WAS INTENDED. WE THEN REQUESTED THE FULL LENGTH OF RWY 27L BECAUSE OF THE JAMMED SPOILER HANDLE. WE WERE TOLD ON LNDG TO CALL ZMA REGARDING THE FLT. THE JAMMED SPOILER HANDLE WAS THE RESULT OF IMPROPER MAINT PROC AT THE PRIOR STATION. THIS CAUSED THE ALTDEV; BUT THE CREW EXPERIENCED SOME FRUSTRATION BECAUSE WE WERE UNABLE TO CONTACT THE CTLR IN THE DSCNT. CTLRS NEED TO ALLOW BREAKS IN THEIR XMISSIONS FOR ACFT TO CONTACT THEM.
